New studies of behaviors of particles containing heavy quarks shed light into what the early universe looked like in its first microseconds.
Simultaneous measurements of x-rays and gamma rays emitted in radioactive nuclear decays show that the vacancy left by an electron’s departure, not the atomic structure, influences whether gamma rays are released.
Seven-year study explains how packets of light are exchanged when protons meet electrons.
The newly upgraded CEBAF Accelerator opens door to strong force studies.
Calculations of a subatomic particle called the sigma provide insight into the communication between subatomic particles deep inside the heart of matter.
Like water, neutrons seek their own level, and watching how they flow may teach us about how the chemical elements were made.
A new high-power green-light laser generates beam-cooling electrons at the Relativistic Heavy Ion Collider.
Scientists obtain new evidence for the existence of the extremely neutron-rich, very short-lived isotope of hydrogen 5H.
Scientists discover new signposts in the quest to determine how matter from the early universe turned into the world we know today.
Electric and magnetic properties of a radioactive atom provide unique insight into the nature of proton and neutron motion.
A new model identifies a high degree of fluctuations in the glue-like particles that bind quarks within protons as essential to explaining proton structure.
